《UNIX編程環境（英文版）》由克尼漢、派克所著，本書旨在傳播UNIX編程哲學。因為這種哲學基於程序之間的關繫，所以我們
必須將大部分篇幅用於討論各個工具，但是自始至終貫穿著組合程序以及利用程序來構建程序的主題。為了很好地使用UNIX繫統及其組件，不僅必須理解如何使用程序，還要理解如何讓它們適應環境。
本書的目標讀者是個體的程序員，希望通過提高他們的工作效率來使工作團隊具有*高的生產率。盡管我們的目標讀者是程序員，但閱讀前四五章並不需要編程經驗，所以這部分內容對其他用戶也是有幫助的。

《UNIX編程環境（英文版）》由克尼漢、派克所著，本書繫UINX編程 領域內的經典暢銷書。作者本著“授之以漁”的態度，不僅向讀者介紹了 UNIX繫統編程的基本技巧及編程規範，更是將UNIX的編程哲學融入其中， 以幫助讀者更加深刻地理解UNIX繫統。《UNIX編程環境（英文版）》的主 要內容包括UNIX繫統基本操作、文件繫統、Shell編程、過濾器、標準I/O 庫編程、繫統調用、程序開發工具、文檔準備工具等。 《UNIX編程環境（英文版）》適合UNIX繫統的初學者以及UNIX繫統編 程的愛好者閱讀。
